CHURN.

SPECIFICATION forming part of Letters Patent No. 764,07 5, dated July 5, 1904.

Application led March 10,1904.

T all whom, it may concern:

Be it known that I, CHARLES SAILOR, a citizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Churns, of which the following is a specification.

My invention relates to that class of churns commonly known as working-body; and 'the object of the invention is to simplify, irn-l io prove, and cheapen the cost of construction, as well as to associate therewith convenience and expedition in the operation of churning and the production of butter.

With these ends in view the invention consists in the novel construction and combination of parts, as will be hereinafter more in detail described, and particularly pointed out in the claims.

In the accompanying drawings, which form 2O a part of this specification and fully illustrate my invention, and which will enable others skilled in the art to which it pertains to make and use the same, Figure 1 is a side view of my churn, showing it suspended from a crossbeam or other suitable fixture. Fig. 2 is a side view, partly in section. Fig. 3 is a side view of the top cap detached from one end of the body of the churn. of the opposite cap, and Fig. 5 is amodication of the rebounding-plug or buffer seated within the respective caps.

Referring by letter to the annexed drawings, A designates the body of a churn one end of which has a neck or contracted portion,

3 5 in this example the form being preferably cylindrical, but if desired it may be of any of the well-known forms of construction, the line m, Fig. l, indicating the height of filling.

B designates a base-cap resembling a frustum of a cone, having a circular ange C formed upon the base or larger portion thereof, and centrally upon said flange is formed a short tube D, the free end of which projects slightly beyond the apex or smaller portion of the frustum of a cone, in which is snugly but removably seated a rubber buier or re'- bound-plug E, the ange C having eyes or hooks F and F secured thereto.

Fig. L is a side view Serial No. 197,436. (No model.)

G designates the opposite or top cap, which 1s also a frustum of a cone, and H is a screw- 'threaded circular flange which is removably secured to the neck I of the contracted portion ofthe body A, said'frustum of a cone terminating at its 'outer or smaller end in a smooth circular ange J, in which is similarly seated another buffer or rebound-plug, K. The screw-threaded flange H of this cap is also provided with eyes or hooks L and L, the eyes or hooks on the flanges of both base and top cap being for a purpose Vhereinafter explained. The top cap G is also provided with vents M and M', having small screwthreaded caps N and N', the threads of which engage corresponding screw-threads in the vents. The object of these vents is by removing the cap from the lupperV or top vent while the churn is suspended the gases which accumulate while churning may thereby escape, it being obvious that one of the capcovered vents is always directly on top when the churn is suspended andin operation. The buttermilk may when the process of churning is complete be withdrawn from churn by removing cap from lower vent without disturbing the position of the churn.

InvFig. 5 I have shown a modification of the buffer in operating the churn in which a buifer O, which may be made of any suitable material, is securely held by means of the free end of a coil-spring P, the opposite end of said spring being secured to and inclosed ina cap or short tube P, which construction, if preferable, may be substituted for the rubber buffers orrebound-plugs alone, as shown and applied to the churn in Figs. l and 2 of the drawings. v

The operation of my invention is as follows: After putting the desired amount of cream in the churn-body A the cap Gr is screwed home, making an unleakable joint. The cap B is placedin position on the opposite end of the churn-body and an endless rope or cord A is hooked into or run through the eyes or hooks secured to the caps.

when it is then looped, as shown, vand carried up to a suitable height and there secured, as

It is obvious that v at R, the weight of the suspended churn and contents will hold the cap B securely in place. The churn may be suspended in a doorway or between two posts set in the ground with a cross-beam at top for the purpose; but in either case or from where suspended it is necessary to be located where there are at convenient distances contacting surfaces for the buffers to act upon, and when the churn is properly iilled and suspended the operator by placing a hand on the churn-body gives it a pendulous motion, causing it to strike alternately against the contacting surfaces and by virtue ofthe rebound caused by the elasticity of the rubber plug, buffer, or coil-spring, as shown, the action is simplified, and the agitation is so great that butter is thereby produced in a very short time with the minimum exertion on the part of the operator, after which the operatormay unscrew the caps from the vents and withdraw the buttermilk without otherwise disturbing the churn, leaving only the butter remaining. The top cap, containing the vents, can then be unscrewed and removed and the butter taken out at the mouth of the churn. Y

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A churn of the character described, the same being provided with the caps B and Gr, the latter having the screw-threaded vents M and M' provided with screw-caps N and N', circular flanges C and H, smaller circular iianges D and J, for the reception of the buffersE and K, screw-threaded flange H having eyes L, L', cap B, circular ange C, eyes F, F' in combination with the body portion A, having one end screw-threaded and endless rope A', substantially as described.

2. A churn comprising the body A, having a screw-threaded contracted end portion and provided with caps B and G, buffersE and K, seated within short tubes in said caps, the cap Gr provided with vents N and N', circular flanges() and G, eyes L, L', secured to said ange, eyes F and F' secured to ange C, rope passed through said eyes whereby the churn is suspended, substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
